Standard ball valves

  • Description :
    Pre-insulated valves can be installed at all points on the network that are free from lateral expansion movements. They are mainly used to isolate networks. The ends of the main pipe are not insulated over a length of 150 mm. Standard valves can be supplied with geared actuators which are included from ND 350, to open and close the valve more easily. Welds on the HDPE sheath are made in the factory. Nordic or DELFIN alarm wires can be inserted into the insulation upon request.
    With the standard wall thicknesses proposed, our valves have a nominal pressure resistance of NP 25.

  • Operating temperature: max. +148 °C continuous
  • Operating pressure: NP 25
  • Diameters: ND 20 to 1000
  • Geared actuator: ND 350 to 1000
  • Compliance: Standard EN 488
